7c citing evidence of how natural selection and its evolutionary consequences provide a scientific explanation for the diversity and unity of past and present life forms on Earth. ">(e.g. Galapagos Islands, Hawaiian Islands, Australia, geographic isolation, adaptive radiation).
-selection can occur for more than one similar population contributing to earth's diversity (stabilizing, directional, disruptive)
8a illustrating that when an environment changes, the survival advantage /disadvantage of some characteristics may change
- environment changes may lead to the selection of extreme versions of the species (directional, disruptive, stabilizing selection)
National Standards:
Standard C: Life Science- develop an understanding of biological evolution (subtopic three).
the ensuing selection by the environment of those offspring better able to survive and leave offspring.
Standard F: Science in Personal and Social Perspectives- develop an understanding of population growth (subtopic 2)
Context of Lesson:
This lesson will introduce the three types of population distributions based on selection, which are: stabilizing, disruptive, and directional. Overview of lesson, including: where it fits in unit, what are key ideas and what will students be doing.

Jelly Bean Lab:
1) Give students assorted colors of jelly beans (equal amounts of three colors- tell them they can collect more colors as populations increase)
2) Assign different scenarios for each group:
